A method for sealing a loss circulation zone of a subterranean well includes delivering a loss circulation product into a wellbore of the subterranean well. The loss circulation product has a solvent, a fibrous material, and a first reactant. The fibrous material traps the first reactant to form a porous cake across a fracture of the loss circulation zone. A second reactant is delivered into the wellbore of the subterranean well, the second reactant passes through the porous cake and reacts with the first reactant, reducing a porosity of the porous cake across the fracture so that the loss circulation product seals the loss circulation zone.

A method includes adding a clay to water to form a suspension of clay in water, the clay including pieces of clay having an average diameter of at least 2 &#x3bc;m; adding a dispersant to the suspension of clay in water to form a drilling fluid; and injecting the drilling fluid into a well. In the drilling fluid, the dispersant interacts with the clay to form nanoscale particles of clay having an average diameter of less than 500 nm.
